a study of fda018-adc in patients with advanced solid tumors

Conditions: Advanced/ Metastatic Solid Tumors

Summary: this is a phase 1, open-label, dose escalation and dose expansion study to evaluate the safety, tolerability, pharmacokinetics and efficacy of fda018-adc in patients with advanced/metastatic solid tumors.

this is a first-in-human (fih), phase 1, open-label, dose escalation and dose expansion study to evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of fda018-adc in patients with advanced/metastatic solid tumors. fda018-adc is administered via intravenous infusion using an accelerated titration method followed by a conventional 3 + 3 study design to identify the maximum tolerated dose (mtd) and dose-limiting toxicities（dlt）during 35-day cycle with 3 doses. in addition, the maximum-tolerated dose and recommended phase ii dose for fda018-adc will be determined.
